Research on Aerodynamic Noise Reduction with Non-smooth Surfaces of Exterior Rearview Mirror Cover

摘要：

　　In order to research the car interior aerodynamic noise,the non-smooth surfaces of exterior rearview mirror are studied based on computational fluid dynamics (CFD) and computational aero acoustic (CAA) method.The large eddy simulation model was used to construct transient flow field,and the FW-H acoustic model was used to analyze the aerodynamic noise generated by the exterior rearview mirror.From the comparative analysis on aerodynamic noise spectrum of every monitor point,a conclusion can be drawn that the rearview mirror with non-smooth surfaces can improve the performance of car interior aerodynamic noise.
